DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0028] Please refer to Figures 1-5 In the embodiments of the utility model, a building heating ventilation device comprises a frame 1, the lower surface of the frame 1 is fixedly provided with a U-shaped frame 103, the inside of the U-shaped frame 103 is slidably connected with a dust collecting plate 104, a filter assembly 2 is movably arranged in the inside of the frame 1, the filter assembly 2 comprises four rotating shafts 201 rotatably connected to the inside of the frame 1, the outside of the four rotating shafts 201 is sleeved with filter screens 202, the filter screens 202 are fixedly provided with chains 203 on both sides, the rotating shafts 201 are fixedly provided with sprockets 204 at both ends of the outside surface, and an air induction assembly 3 is fixedly arranged on the inside surface of the frame 1.

[0029] Specifically, the fan 107 operates to draw air from the inside to the outside to extract flue gas, and the filter assembly 2 filters the soot so that the soot moves to the other side of the fan 107 along the filter screen 202 and is blown out to the outside.

[0030] Embodiment one

[0031] As shown in Figure 1 and Figure 2 In this embodiment, the frame 1 is symmetrically provided with sliding grooves 101 on both sides, the inside of the two sliding grooves 101 is symmetrically slidably connected with baffles 102, and the lower surface of the frame 1 is provided with a through groove 105.

[0032] In this embodiment, the baffle 102 is slid through the sliding groove 101. When the two baffles 102 are closed, the frame 1 is closed, so that indoor and outdoor air does not circulate. When the baffle 102 is opened, indoor and outdoor air circulates. The through groove 105 allows part of the soot on the surface of the filter screen 202 to fall onto the soot receiving plate 104. The air is discharged to the outside by the air induction assembly 3.

[0033] As shown in Figure 3 and Figure 5 In this embodiment, the sealing frame 106 is fixedly installed on the inner side surface of the frame 1 and is attached to the filter screen 202. The fan 107 is fixedly installed on the inner surface of the frame 1 and is located inside the filter screen 202. The plurality of sprockets 204 are in meshing transmission connection with the corresponding positions of the chain 203. The second belt transmission assembly 206 is fixedly installed on one end of the outer side surface of the two rotating shafts 201 near the top and bottom of the frame 1. The first belt transmission assembly 205 is fixedly installed on one end of the outer side surface of the two rotating shafts 201 near the sliding groove 101. The motor 207 is fixedly installed on one side surface of the inside of the frame 1. The output end of the motor 207 and the outer side surface of one rotating shaft 201 are fixedly installed with the gear 208. The two gears 208 are in meshing transmission connection.

[0034] In specific implementation, the first belt transmission assembly 205 and the second belt transmission assembly 206 are both synchronous belt structures, so that the plurality of rotating shafts 201 can rotate synchronously. When the motor 207 operates, one rotating shaft 201 rotates through the transmission of the gear 208. Then, the two rotating shafts 201 located below rotate synchronously through the transmission of the second belt transmission assembly 206 below. The two rotating shafts 201 on the same side rotate through the transmission of the first belt transmission assembly 205. At this time, the two rotating shafts 201 below and the rotating shaft 201 above rotate synchronously. Then, the four rotating shafts 201 rotate synchronously through the transmission of the second belt transmission assembly 206 above. The plurality of sprockets 204 rotate together. The filter screen 202 rotates through the meshing transmission of the sprocket 204 and the chain 203. The position of the filter screen 202 is adjusted. After the filter screen 202 is located on the indoor side and has soot, it is rotated to the outdoor side, so that it is discharged with the flow of air. Thus, the dust in the air is filtered through the filter screen 202. When the indoor is heated and the indoor personnel need to smoke, the personnel move to the ventilation device, pull open the soot receiving plate 104 to receive the falling soot, and the second-hand smoke is discharged to the outside by the fan 107. At the same time, part of the soot floating in the air is adsorbed to the surface of the filter screen 202. The soot on the surface of the filter screen 202 can also be discharged to the outside by adjusting the position of the filter screen 202. Thus, the second-hand smoke in the room is avoided from being inhaled into the body, the health of the body is improved, and the indoor air quality is improved.

[0035] Embodiment Two

[0036] On the basis of embodiment one, in order to solve the problem that the soot on the surface of the soot receiving plate 104 is not easy to discharge.

[0037] As Figure 4 shown, in the present embodiment, the air induction assembly 3 comprises: a multi-way pipe 301 fixedly embedded and installed in the inner lower surface of the frame body 1, a U-shaped pipe 303 located in the U-shaped frame 103 and fixedly communicated with the multi-way pipe 301; an air inlet groove 302 is formed on the outer surface of the multi-way pipe 301, and a plurality of air distribution holes 304 are equidistantly formed on the outer surface of the U-shaped pipe 303.

[0038] In specific implementation, the air driven by the fan 107 enters the inside of the multi-way pipe 301 through the air inlet groove 302, then enters the inside of the U-shaped pipe 303, and is discharged from the plurality of air distribution holes 304, so that the air blows to the dust collecting plate 104 and blows the ash on the surface of the dust collecting plate 104 to the outside.

[0039] It is apparent for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, but can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be considered in all aspects as exemplary and non-restrictive, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and range of the equivalent elements of the claims are intended to be embraced in the present application.
